It can be hard for a woman to separate sex from attraction. She wont feel attractive because you aren't sleeping with her. I had an ex that would only touch me if he was wearing gloves. He worked as a massage therapist and was worried about getting it on his hands. I can tell you the shame I felt everytime he put on gloves was overwhelming. It was why I stopped anything other than straight sex. (Yes I was in antivirals and we used protection.) I had given him this website for information, but I don't know what he found by searching online.
However, knowing your past she should have been as understanding. Sharing your body with someone after a history of sexual abuse takes trust. It is possible that she missed how much it effected YOU in her anxiety over her disclosure. Purely speculation on my part but I bet she discussed it with her girlfriends but didn't reveal your secret because it was personal, so the "help" she got from her friends was skewed. Who knows for sure.
I hope you hear from her and hopefully it all ends well.
